Research On V2X Beamforming And Tracking Method Based On Millimeter Wave Energy Angle

V2X communication is an important technical means that constitutes the Internet of Vehicles and its constituent carrier intelligent networked vehicles.The time-varying of the location of the communication entity and its motion state in V2X communication poses a huge challenge to the real-time and reliability of such communication.V2X communication needs to ensure that the communication entity establishes a connection with the network in the direction that meets the access conditions and transmits data stably.The determination and determination of the angular positional relationship between the communication entities,and the energy angle-based beamforming and beam tracking mechanisms established by considering the transmission and reception power of the angular relationship between the communication entities,are stable and reliable for ensuring continuity between the V2X communication entities.Connections are important.At present,the research on V2X communication beamforming and beam tracking technology at home and abroad is not deep enough.Most of the research focused on the macro discussion of the V2X communication standard,or the specific design of the access antenna,or the discussion of the single problem of access beamforming and beam tracking,lacking the perspective of maintaining a stable connection between communicating entities.Examine the methodology of V2X communication.Based on the applicability of millimeter wave to V2X communication system,this paper first proposes an energy angle based beamforming theory based on millimeter wave for realizing communication quality and efficient access in V2X communication scenarios.The basic process of beamforming and the quantitative evaluation mechanism are given quantitatively,and the effectiveness of the proposed beamforming theory is proved by simulation analysis.Then,based on the above-mentioned beamforming theory,based on theabove-mentioned beamforming theory,a multi-decision beam tracking(MDBT)scheme based on energy angle is proposed to maintain stable data transmission between mobiles.Real-time directional connection,and the effectiveness and superiority of the proposed beam tracking method are proved by simulation analysis.Finally,based on the theory of beamforming and tracking proposed in the paper,the effects of the proposed millimeter-wave based V2X communication system beamforming and tracking method are simulated and analyzed,and a scene-based real vehicle test system is constructed.The beamforming mechanism based on energy angle hybrid precoding in the real vehicle implementation of V2X communication is proved to be based on the practicality of millimeter wave V2X communication in the process of comparison with the simulation conclusion.
